Scan to PDF: Sign & Redact for iPhone and Android

Overview

What it is, in plain words.

Scan to PDF: Sign & Redact turns any paper into a clean PDF, lets you fill in and sign it with your finger and permanently blacks out sensitive details. The blackout is burned into the exported file instead of sitting on a removable layer. Everything runs on your phone, with no account, no watermark and no cloud.

What is it?

Scan to PDF: Sign & Redact is a document scanner with signing, redaction and OCR that works entirely on your device.

What problem does it solve?

Sharing a bank statement, pay stub or ID copy usually exposes more than the recipient needs, and a black box drawn over text in a PDF can often be removed. This app flattens the redaction into the exported PDF and lets you sign without printing anything.

Privacy and permissions

Private by design.

The store listing says your documents never leave your phone, with no cloud, upload, tracking, sign-up, watermark or subscription needed, and that the App Store privacy label is Data Not Collected. The listings mention the camera for scanning and Face ID or fingerprint to lock the library, and the app works fully offline.
